Abstract:
The title com-pound, C15H11NO5, is relatively planar, with the planes of the two aromatic rings being inclined to each other by 3.09 (5)°. In the crystal, mol-ecules are linked by a pair of C-H⋯O hydrogen bonds, forming inversion dimers, which enclose an R 2 2(16) ring motif. The dimers are linked by a further pair of C-H⋯O hydrogen-bonds forming ribbons enclosing R 4 4(26) ring motifs. The ribbons are linked by offset π-π inter-actions [centroid-centroid distances = 3.6754 (6)-3.7519 (6) Å] to form layers parallel to the ac plane. Through Hirshfeld surface analyses, the d norm surfaces, electrostatic potential and two-dimensional fingerprint (FP) plots were examined to verify the contributions of the different inter-molecular contacts within the supra-molecular structure. The shape-index surface shows that two sides of the mol-ecule are involved with the same contacts in neighbouring mol-ecules, and the curvedness plot shows flat surface patches that are characteristic of planar stacking.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
